In AWStats through 7.8, cgi-bin/awstats.pl?config= accepts a partial absolute pathname (omitting the initial /etc), even though it was intended to only read a file in the /etc/awstats/awstats.conf format. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501 and CVE-2020-29600.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the bba3f684-9b1d-11ed-9a3f-b42e991fc52e advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4953-1 advisory.

Update to AWStats 7.8. Includes security fix for CVE-2020-29600 / CVE-2020-35176

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that Awstats, a web server log analyzer, was vulnerable to path traversal attacks. A remote unauthenticated attacker could leverage that to perform arbitrary code execution. The previous fix did not fully address the issue when the default /etc/awstats/awstats.conf is not present.

For Debian 9 stretch, this problem has been fixed in version 7.6+dfsg-1+deb9u2.

We recommend that you upgrade your awstats packages.
